Y tion.

In the drawings, Figure 1 represents a sec- `tional view on the line offr no in Fig. 3, showing the pivotal connection of the parts andexposing the spring which holds the top in position when closed or openfor use. Fig. 2 is, a side view showing position of device when closed,the dotted lines showing position of the top when open, also showingslot and set-screw for adjusting the parts shown in Fig. l; and' Fig. 3is a top View of the device when open.

Similar letters of reference indicate corresponding parts.

This invention relates to bottle-Stoppers which are designed to excludefrom the con tents of a bottle extraneous matter, as insects, dust, &c.,and to facilitate the rapid and convenient handling of the same bybarkeepers, waiters, and other persons.

It consists in the construction andarrangement of the parts of abottle-stopper designed to be secured to the neck of abottle, whereby itmay be readily opened for the reception or delivery of its contents orclosed to protect the same, as will be fully described on reference tothe drawings and claimed.

In the drawings, B, C, l), and E represent four parts of a stopper madeof any suitable material and of a proper form to open and close the sameby turning the part- C on its pivot, thereby throwing the top into anopen position at the side of the lip of the. bottle. The part E is acollar clamped to the neck of the bottle A by a screw e.A The partD isan upright slotted shank secured to the collar E by an adjustingset-screw d and pivoted to the part (l by the pivot c. The part C is aplate which 'is pivoted to the part D and hinged to the part B. ThepartB is a diskshaped cover hinged to the plate C and-held in positionby the spring '19.

The parts of the `device are operated by using the thumb or finger topush the hinged parts B and C sidewise, whereby the cover B will beniade to take a position at the side of the lip of the bottle and beiirnilyheld there by the spring h for the reception or delivery of thecontents, and by the reverse movement the bottle may be closed.

Having thus described my iuvention,what

I claim as new, and desire to secure by Letters Patent, isj Thecombination of the cover B, hinged to the plate C, and a spring'engaging the cover and plate and arranged to swing the cover toward theplate. to hold the same on the mouth of the bottle or against the neckthereof, and the plate C, pivoted to the upright slotted shank D, whichis adj ustablyarranged to the collar E by a set-screw (l, as set forth.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 5th day of January, 1891.
